Read this excerpt from Exploring the Titanic.

Alvin could only dive to 6,000 feet. Since the average depth of the deep ocean is about 12,000 feet, the Navy decided to give it a new hull of titanium alloy, a very strong metal that could hold up to huge underwater pressures and allow us to dive to 13,000 feet. By chance, this refitting project was called Project Titanus.

Titanium, Titanus, Titanic – that started me thinking. The Titanic was thought to lie at a depth of just over 12,000 feet.

Based on the excerpt, why does the author include the name of the refitting project?

to explain how Alvin was similar to the Titanic

to show how titanium was found inside the Titanic

to connect Alvin with the author’s search for the Titanic

to describe how Project Titanus was named after the Titanic

modifying the base for word

1)they use panels

2)they include images and words.

3)they contain gutters.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
